What is mutual exclusivity in early word learning?

• A. The assumption that objects have only one label; children map new words to unfamiliar objects.
• B. The belief that everything has multiple labels.
• C. The rule that nouns must precede verbs.
• D. A preference for using gestures over words.

Answer: (A)

Mutual exclusivity is the bias children use in word learning that each object has only one label. When they hear a new word in a situation with a familiar object that already has a name and an unfamiliar object, they tend to map the new word to the unfamiliar object rather than to the object that already has a known label. This helps them quickly expand vocabulary by disambiguating which object the new word should refer to. For example, if a child sees a familiar ball and an unfamiliar toy and hears a novel word like “blicket,” they are likely to attach “blicket” to the unfamiliar toy, not the ball, because the ball already has a name. This concept is distinct from ideas about grammar order or preferences for gestures, and it isn’t about everything having multiple labels; it specifically describes how children decide which object a new word refers to in the moment of mapping.
